Document Type and Number:
WIPO Patent Application WO/2021/217760
Kind Code:
A1
Abstract:
Disclosed are a display panel and a display device. The display panel comprises a first substrate and a second substrate arranged opposite to each other. A liquid crystal layer is provided between the first substrate and the second substrate. A chiral agent is doped in the liquid crystal layer. According to the present application, a chiral agent is doped in a liquid crystal layer of a display panel. A helical twisting power generated by the chiral agent is used to drive liquid crystal molecules around a pixel to rotate, which can narrow the dark fringe area around the pixel, and improve the transmittance of the display panel.
